What you have heard is right, it is not DAX. Instead, it is based off of DAX's work. It is still unknown who is the creator of this firmware. This time, it's no patch, it's the real thing. This release includes in-XMB recovery.

Changes:

Uses the 3.93 kernel

Same ol' same ol' custom firmware features.

Ability to use the normal recovery inside the XMB by pressing the HOME button:

• When in the recovery, the system is suspended, and you can change all options directly.
• All options work immediately, there is no need to reboot
• Ability to make a Pandora battery from the recovery, read and restore the EEPROM, etc. Providing that the motherboard supports it.
• Ability to hide the MAC address in System Information, if you do so, the MAC will show visually as all 0’s.
• Ability to save the savegames in normal format, rather then encrypted (only functions in March33 and Sony NP9960 mode).

• The native 3.93 pops isn’t as good as the previous pops; therefore hopefully the popsloader will get updated to support 3.93.

1.50 Kernel:

• Install kernel 1.50 on a PSP Fat. To use the 1.50 kernel for an application, you will DEFINATELY need to put the kernel to 1.50, even if the application is in the GAME150 directory. If you change the kernel in VSH Recovery, you’ll still need a reboot.
• The new recovery has these two asked features:
  • Suspend device
  • Shutdown device

Keep in mind that a just newly release CFW is like a box of chocolates, you never know watcha' gunnu get! It's up to you and you only if you want to take the risk and upgrade.

WARNING!!!

DO NOT LEAVE YOUR PSP UNATTENDED WHILE DOING THIS UPDATE, YOU WILL NEED TO PRESS "X" RIGHT AFTER THE SONY INSTALLER IS OVER OR ELSE YOU WILL GET A BRICK!
